Scenic 2 various problems

Hello good, to see if someone can help me, since a while I observe that my senic 2 does not throw water through the holes of the clean, or it arrives without force, and the rear or arrives, the engine sounds, so I rule out the motor, and it has no leaks where it loses it. And the other is a noise under splash together with a glove.

Friend of the water of the clean, you must clean the exit holes, most likely they are covered with tartar and nothing else, and with respect to the noise you will detrminate if it is metallic or plastic because you want to do not have to disassemble anything and you can work below and now.

You may have the Ò tube Ò Motor Aspiration Filter, stuck and it is easy that just clean it.

The holes are not covered since you blow through the tube and leaves perfectly, and to disassemble the access below is impracticable, with what remains more remedy to disassemble bumpers to access the cleaning engine. Thank you to answer

That is what I have left to look, it was in case I avoided having to disassemble the bumper, to access the tardrobrisas engine. Thank you
